This two stepas are the only relevant ones to achieve the Dom0 memory

restriction.

While booting, you should have interacted with Grub, checking if the

parameter dom0_mem is really present in the right place. There you would

probably find that it is not.

The variable used to set Dom0 memory is slightly different:

GRUB_CMDLINE_XEN="dom0_mem=4032"

It appears my system could fall into this link:

If I set my system to around 2G or lower, it appears correct, but if I start going above 2G, even

up into the teens of Gigabytes, I see lost RAM.

So, until Wheezy becomes stable, I'll stick with Dom0 at 2G.

Thanks!

Cheers,

Mike
